Edit: If you do not like the proposed offer, you are free to give a suggestion for possible valuations for the thread creator to consider rather than produce a comment that does not give an offer for them to consider. The thread creator does not have to accept it, but it is better than calling them out as different players valuate cards differently.

If you do not like the offer and do not have any constructive suggestions, please refrain from commenting on the thread. Thank you for your understanding.

My constructive suggestion is to offer values close to the market price. When dealing with big amounts of cards such as these. 5k difference either high or low makes a big difference and here the deal has some cards with a 30k difference from the market value. I suggest sticking close to the market value and that way you will have a deal with a player.
